Typing Rhythm Test
Type the passage — dwell time, flight time, and bigram heatmap update as you type.

How to use
- Click the textarea and type the fixed passage from the first character to the end without skipping ahead incorrectly — progress follows correct-prefix matching.
- Watch live avg dwell, avg flight, and consistency while you type.
- Review the bigram heatmap (scrollable) — color shows relative flight speed per letter pair.
- Complete the full passage to unlock the final rhythm score, fastest/slowest bigrams, and a rating band.
- Click Reset to clear stats and type the passage again.
FAQ
What is dwell vs flight time?
Dwell is how long you hold a key down. Flight is the gap from releasing one key to pressing the next — bigram flight powers the heatmap.
Is data uploaded?
No. Timing is computed locally from keyboard events in your tab.
Introduction
Typing Rhythm Test analyzes keystroke timing: how long you hold keys (dwell), gaps between keys (flight), a per-bigram heatmap, and a consistency score derived from flight-time variation.
Purpose
- See which letter pairs slow you down.
- Train steadier rhythm independent of raw WPM.
Key Features
- Per-keystroke dwell and flight timing with a scrollable bigram heatmap.
- Consistency score derived from flight-time variation.
- Final report with fastest/slowest pairs and qualitative rating bands.
Common Use Cases
- Identifying weak letter transitions for targeted practice.
- Coaching ergonomics — uneven rhythm often correlates with tension or layout issues.
Best Practices
- Type the passage from the first character in order; mistakes stall forward progress.
- Complete the full passage to unlock the most reliable aggregate stats.
Comparison metrics
| Metric | Meaning |
|---|---|
| Avg dwell (ms) | Mean hold time per key release — compare across sessions on the same passage. |
| Avg flight (ms) | Mean time between key releases and the next press. |
| Consistency (0–100) | Higher when flight times are less variable (lower relative standard deviation). |
| Bigram heatmap | Longer bars / warmer colors for slower bigrams on average. |
| Final score & rating | One composite consistency score plus Expert / Proficient / Average / Developing bands at the end of the passage. |
